Single Arm Professional Repair Stand Pro Shop Quick-Release

The Single Arm Pro Stand with the Pro Shop quick-release clamp is the workhorse single-arm shop stand fitted for high-throughput bike-to-bike workflow. Same 36 kg base-and-column mass under the same 30 kg working capacity as the manually adjustable variant; the difference lives in the clamp head. Squeeze the Pro Shop clamp's jaws by hand and they already grip the tube with enough force to hold the bike; a turn of the handle adds clamping tension, and the quick-release button opens the jaws once the handle is backed off. There is no jaw-width screw to re-dial, so a mechanic working through a service queue isn't resetting the clamp for every bike.

For a shop seeing twenty-plus bikes through the floor on a Saturday, the QR clamp is the working detail that pays back fastest. Back the handle off, press the quick-release button, and the bike is out; squeeze the jaws onto the next bike's seatpost and it is already held while the handle sets the final tension. Because the jaws take any tube shape from 22 to 60 mm straight off the squeeze, there is no jaw-opening adjustment between a kid's bike and a fat-tubed e-MTB.

The Single Arm Pro Stand body is a single column on a fixed base plate with 726 x 572 mm of floor contact; the design is conservative for a reason, and the 36 kg base-and-column mass is what makes the column stay vertical when a heavy bike loads it eccentrically. The clamp pressure on the QR is adjustable through the full range from “light grip on carbon” to “shop-grade hold on a wet aluminum tube”; the QR mechanism is mechanical (no electronics, no batteries) and built to outlast the rest of the shop fixtures.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race teams. The Single Arm Pro Stand is one of the catalog items that hasn't needed redesign in a decade; the 36 kg base does its job, the column geometry has been refined over multiple production runs, and the Pro Shop QR clamp on top is the same head Unior fits to its quick-release BikeGator portable, and Unior states the clamp is compatible with all of its repair stands. What makes the Single Arm a shop stand rather than a portable is the base.

Pro tip from our mechanics

The Single Arm Pro Shop QR is what we recommend when a one-mechanic shop or a serious home builder asks for a stand that will outlast the building it's installed in. The 36 kg base is overkill for a one-bike home garage, but it's not overkill for a working mechanic; the column doesn't wobble under a hard pry on a stuck pedal, and the clamp doesn't slip on a wet seatpost. The QR-versus-cam decision is mostly about how often the stand sees a new bike: How to choose a bike repair stand →

FAQ

How does the Pro Shop quick-release clamp hold and release a bike? Squeeze the jaws by hand — the quick-release system already grips the seatpost with enough force to hold the bike — then rotate the handle to apply the final clamping tension. To release, back the tension off with the handle first, then press the quick-release button and the jaws open.

What tube sizes and shapes does the clamp accept? The jaws grip tubes of any shape from 22 mm to 60 mm in diameter, and the 70 mm jaw height works with short seatposts and dropper posts. Some bike manufacturers advise against clamping thin-walled carbon frames, so ask the bike maker for the recommended clamping point and clean the tube before clamping.

How tall is the 1693BQ, and how much bike can it hold? The column adjusts between 985 mm and 1570 mm, topping out around 1700 mm overall, on a 726 x 572 mm fixed base plate. The stand itself weighs 36 kg and is rated for bikes up to 30 kg, which covers heavier bikes.

How does this stand ship, and what parts are replaceable? It ships as oversized freight: it is excluded from the free-shipping-over-$75 offer, and shipping is charged at carrier cost at checkout. The rubber jaw covers are a replaceable wear part (Unior item 1693.11), and the matching 1693.3-US tool tray is sold separately.
